They don’t head back to the ballroom for another few weeks, but Derek Hough, Karina Smirnoff and Cheryl Burke already look to be in top form.

The Dancing with the Stars pros were able to relax – and flash their fit physiques – with a little fun in the sun over the weekend in Las Vegas.

The Asahi Super Dry Beer summer takeover kicked off Friday at Marquee Nightclub, where the trio, sat at a VIP table and drank beer. The fun continued on Saturday at Marquee Dayclub, where the pros chilled in a poolside cabana while listening to the sounds of the EC Twins, who provided the soundtrack to the party.

“They all were having a great time, relaxing before the season starts up,” a source tells PEOPLE. “There were times when you would see Karina and Derek jump behind the deejay booth, taking photos along with dancing and laughing.”
